Abstract

Hand-held radiometers that measure reflected solar and emitted thermal radiation are useful for evaluating agronomic parameters. An example application is presented which shows that thermal measurements can detect water stress before visual signs appear. Reflected solar measurements can be used to document the history of stress, and are useful for calibrating the thermal parameter at various degrees of stress. Some special requirements of instruments that are to be used in field experiments are discussed.
